摘要
介绍砌块仿花岗岩挡土结构的特点和砌块形状,针对砌块挡土结构在我国刚开始应用,没有设计、施工规范的现状,依托可以借鉴的加筋挡土结构和浆砌块石挡土结构设计规范,提出了自锁式砌块加筋挡土结构设计中的地面荷载强度及土压力计算方法、砌块层间稳定验算方法、加筋长度和间距验算方法、挡土结构整体稳定验算方法和施工过程中需要注意的主要问题,为自锁式砌块加筋挡土结构设计人员提供了设计验算内容、验算方法和安全系数取值范围,为现场施工和监理人员提供参考,并为该类型的挡土结构推广应用提供技术支持。
An introduction was given to the characteristics of the granitiform retaining wall and the shape of blocks. Based on the design codes of reinforced concrete block retaining wall and stone masonry retaining wall, the calculation methods for surface loads and earth pressure, the checking methods for the stability between block Myers, the length and spacing of geotextile, and the integral stability of the retaining wall were proposed for design of the self-locked granitiform reinforced concrete block retaining wall, and some problems which should be paid much attention in the construction were put forward. The present method could-provide designers with rational ranges and calculation methods of safety factors for such type of retaining wall, and it was of certain reference values to construction personnel and supervisors. Moreover, the results of study also provided technical support for application and popularization of such type of retaining wall.
